SEALING DEVICE.

T 0 all w]: 0722 it may concern:

Be it known that I, Voarfiorr Poo, a citi Zen of the CZecho-SlovakRepublic, residing at Prague-Vinohrady, in Bohemia, have inventedcertain new and useful Tmpr0vements in Sealing Devices (for which I havefiled an application in Germany on July 30, 1917, patented June 21,1918, No. 307,830), or which the following is a specification.

This invention relates to devices for sealing car doors, trunks, andreceptacles and other objects of various kinds, and the inventionconsists in providing a metallic strip having at its ends lockingdevices which, when united, cannot be separated, it being necessary tobreak or cut the strip in order to detach the sealing device from theobject to which it is applied or to open the object.

My improvements are illustratedL in the accompanying drawings, in whichFigure 1 is an elevation of the sealing device and illustrates how oneside thereof is embossed to indicate the numbers of the months in theyear and the days of the month.

Figure 2 is an elevation of the rear side of the sealing device.

Figure 3 is a perspective view of the sealdevice with the lockingdevices connected.

Figure 4 is a plan view of the blank from which part of the sealingdevice is made.

Figure 5 is a sectional view of the device.

Figure 6 is a detail view showing particu* larly how one member of thelocking device is connected with the strip.

Figure 7 is a detail view in section, showing how the locking devicesare connected.

A indicates a strip of metal having enlarged ends B, C which arecircular in outline. Figure 4 illustrates the blank of metal from whichthe-parts A, B, and 0, shown in Figures 1 and 2, are made. The metalstrip is numbered from 1 to 81 as shown in Figure 1 to indicate the daysof the month, and it is also numbered from 1 to the numbers of themonths. The locking devices are applied to the parts B and C in themanner now to be described.

One member D of the locking device is similar in construction to thesocket member of a non-separable button of the kind generally calledbatchelor buttons. This member comprises a frame d, the bottom of which12 to indicate has an opening d in it. The other member E of thefastening c to which is applied a pin or shank c. The member D isprovided with spring locking devices 6Z2 of the usual kind, and thearrangement is such that when the shank e is inserted through the hole(Z and extended )7 1st the locking devices, the two members of thefastener will be so connected that they cannot be separated and it isnecessary to break the device or cut the strip A in order that it may beseparated from the object to which it is applied. The parts A and B maybear any suitable designation, such as the number of the seal and theplace of consignment or destination. The device may be applied to a cardoor in obvious ways and it may be applied to a trunk, box, or otherreceptacles in any way desired. The proper month and the proper day ofthe month may be punched from the strip by a suitable tool.

It will be observed that the construction s such that it is notnecessary to use any tool when the sealing device is applied, as the twomembers of the locking device may be brought together and locked by thehands of the attendant alone, but it does require a suitable tool todetach the sealing device from the object to which it is applied as thelocking devices cannot be separated without being deformed or broken andthe metal strip is of such strength that it cannot be broken without theuse of a tool.

The particular way in which the locking devices are connected with thestrip is important. The circular part B is made of somewhat largerdiameter than the member I), so that its edge or periphery may be turnedunder the upper edge of the member D as illustrated, and it will beobserved that at the point I) the metal is so bent that it crosses theedge of the member D and is so connected therewith that it is notpossible to insert a knife or other tool to efi'ect the separation ofthe metal strip from the looking device.

Similarly the member C of the strip is of such size that its edge orperipheral portion 6 be bent over the edge of the frame 6 of this memberand the metal is so bent at e that a knife or tool cannot be inserted toeffect the separation of the strip from the locking member.

The sealing device is simple in construcdevice comprises a frame tion,fulfills all necessary requirements, can be cheaply manufactured, andsold at small cost.

I claim as my invention z 1. A sealing device, comprising a metal stripformed With enlarged ends which are permanently connected to lockingmembers, one member of said locking device comprising a frame, theperipheral portion of which is embraced by one of said enlarged ends andwhich contains locking springs, and the other member having the edge ofits frame embraced by a peripheral portion of the other enlarged end ofthe strip, and said last mentioned locking member having a shank whichis adapted to enter said socket men1- ber.

2. A sealing device, comprising a metal strip permanently connected atits ends to locking devices, one member ofsaid locking device comprisinga frame, the peripheral portion of which is embraced by an enlargedportion of the strip and which contains locking springs, and the othermember of which has the edge of its frame embraced by a peripheralportion of an enlarged part of the strip, and said last mentioned memberhaving a shank which is adapted to'enter said socket member.

3. A sealing device, comprising a metal strip, permanently connected atits ends to locking devices, one member of said locking devicescomprising a frame the peripheral portion of which is embraced by anenlarged portion of the strip, and the other member of which has theedge of its frame embraced by a peripheral portion of an enlarged partof the strip, the frame of the first-mentioned member of the lockingdevices being adapted to enter the frame of the other member of saiddevices.

5. A sealing device, comprising a metal strip having at one end anenlarged portion, a locking device the peripheral portion of which isembraced by the enlarged portion of the strip whereby the joint of theframe is closed to prevent the entrance of a tool, the opposite end ofsaid strip being also formed with an enlarged portion engaging theperipheral portion of the second mem ber of the locking devices, saidlocking device members being arranged to project one into the other, forthe purpose specified.

In testimony whereof, I have hereunto subscribed my name.
